What Factors Should You Consider When Choosing the Best Bleaching Kit for Dyed Hair?
When choosing the best bleaching kit for dyed hair, consider factors such as hair type, developer strength, formula ingredients, ease of application, and aftercare products.
Key factors to consider:
1. Hair type and condition
2. Developer strength
3. Ingredients in the bleaching formula
4. Application method
5. Aftercare products availability
Understanding these factors will ensure that you select the most suitable bleaching kit for your specific needs, especially when dealing with dyed hair.
-
Hair Type and Condition:
Choosing a bleaching kit should start with an assessment of your hair’s type and condition. Hair type could be straight, wavy, or curly, and each type responds differently to bleach. Additionally, the condition of previously dyed hair impacts how it reacts to bleaching. Damaged hair may require gentler products. According to a 2021 study by Masterson et al., different hair types experience varying levels of damage when exposed to bleach, which highlights the importance of choosing a product that matches your hair’s unique needs. -
Developer Strength:
The developer’s strength is measured in volumes and determines how light the hair will become. A 10-volume developer offers a slight lift, while a 40-volume developer provides the most substantial lightening effect. However, a higher volume can cause more damage, especially to already dyed hair. The American Academy of Dermatology emphasizes using lower volumes for more fragile, dyed hair to minimize potential harm. -
Ingredients in the Bleaching Formula:
Bleaching kits contain varying ingredients that may affect results and hair health. Look for kits with nourishing ingredients like oils or proteins that can help protect hair during the bleaching process. Some formulas may also include conditioning agents that can lessen damage. A 2020 review by Johnson et al. indicated that bleach formulations with added moisture can significantly reduce breakage and improve overall hair texture post-bleaching. -
Application Method:
Choose a bleaching kit that offers an application method you feel comfortable with. Some kits include brushes and bowls for precise application, while others may have easier-to-use bottles for all-over application. Ease of application can influence how evenly the bleach is distributed, resulting in better color outcomes. For instance, a study in the Journal of Cosmetic Science argued that even application leads to less patchiness and more satisfying results. -
Aftercare Products Availability:
Post-bleach care is crucial for maintaining hair health. Many bleaching kits come with conditioning treatments or recommend specific aftercare products to help mitigate damage. Consider whether these products are adequate and accessible. The importance of aftercare is highlighted by the Hair Industry Association, which suggests that aftercare can significantly affect hair recovery and maintain color vibrancy after bleaching.
Taking these factors into account will help you select the best bleaching kit tailored for your dyed hair, maximizing both results and hair health.
How Do Ingredients in Bleaching Kits Affect Dyed Hair?
Ingredients in bleaching kits can significantly affect dyed hair by altering its structure, moisture content, and overall health. The primary ingredients in these kits—bleaching agents, conditioners, and additives—interact in specific ways that can lead to damage if not used properly.
-
Hydrogen Peroxide: This is a common bleaching agent that penetrates the hair shaft. It breaks down the natural pigment in hair to lighten its color. Prolonged exposure can weaken hair by breaking down the protein structure, leading to brittleness and breakage. A study by Zohar et al. (2019) noted that overuse can cause significant damage to hair elasticity.
-
Ammonia: This ingredient helps open the cuticle layer of the hair, allowing the bleaching agents to reach the inner layers. However, ammonia can also lead to increased porosity and dryness of the hair. According to research conducted by Matzuzaki et al. (2020), high levels of ammonia can cause strand loss and make hair more susceptible to environmental damage.
-
Conditioners: Many bleaching kits include conditioning agents aimed at minimizing damage. These may contain silicones, oils, and proteins to help maintain moisture and strength. When used correctly, these conditioners can mitigate some drying effects of bleach by replenishing moisture and sealing the cuticle layer.
-
pH Balancers: These ingredients help stabilize the formula and can affect hair’s porosity. A higher pH can result in more opened cuticles, which may lead to more significant damage and moisture loss. Studies indicate a pH range of 9 to 11 in bleaching products, which is considerably higher than the natural pH of hair (around 4.5 to 5.5), contributing to potential hair damage (Keratin Research, 2021).
-
Additives: Some kits include fortifying agents or antioxidants to protect hair during the bleaching process. Ingredients like vitamin E and keratin can help replenish lost nutrients and provide a protective barrier. Research by Takemura et al. (2018) has shown that antioxidants can help reduce oxidative stress on hair fibers during bleaching.
Understanding these ingredient effects is crucial for anyone considering using a bleaching kit on dyed hair. Proper application, along with quality aftercare, can reduce damage and maintain hair health.

- Bleaching Kits for Coarse Hair
- Bleaching Kits for Damaged Hair
The following sections provide detailed explanations of each type of bleaching kit, focusing on their specific attributes and suitability for different hair types.
-
Bleaching Kits for Dark Hair: Bleaching kits for dark hair are formulated to lift more pigment compared to other types. These kits usually contain higher levels of peroxide, which accelerates color lifting. Brands like Clairol and L’Oreal provide specific products for dark hair. A study by Smith et al. (2021) found that users of these kits achieved up to five levels of lift, which is often necessary for effectively reaching blonde shades from darker base colors.
-
Bleaching Kits for Fine Hair: Bleaching kits for fine hair are designed with gentler formulas to minimize damage. These products often contain nourishing ingredients to protect hair strands. For instance, the Wella Blondor Lightening Kit explicitly states that it is suitable for fine hair. According to a survey conducted by Chemical Industry Research (2022), 78% of users reported less breakage when using these specially formulated kits.
-
Bleaching Kits for Coarse Hair: Coarse hair requires stronger bleaching kits due to its denser structure. These kits often have a higher lift ability and may include additives that combat dryness. The Schwarzkopf Essence Ultime kit is favored for its effectiveness on coarse types. A case study by Johnson (2020) highlighted that such kits can lighten hair significantly without compromising texture when used properly.
-
Bleaching Kits for Damaged Hair: Bleach kits for damaged hair focus on repairing and conditioning while lightening. They typically contain bond-building technologies, like Olaplex, which protect the hair’s structure during the bleaching process. The effectiveness of these kits was underscored in research by Lee et al. (2023), where users noted improved hair health post-bleach when using products with bond-building components.
How Can You Safely Use a Bleaching Kit on Previously Dyed Hair?
To safely use a bleaching kit on previously dyed hair, follow these key steps: assess your hair’s health, conduct a strand test, choose a suitable bleaching kit, and apply the product carefully.
Assessing hair health: Before bleaching, evaluate the condition of your hair. Look for signs of damage, such as split ends or dryness. Healthy hair can better withstand the chemical process. If your hair feels very weak or brittle, consider strengthening treatments before bleaching.
Conducting a strand test: Always perform a strand test to check how your hair reacts to the bleach. Choose a small section of hair, apply the bleach, and observe the results after the recommended development time. This test helps determine the suitability of the product and the time needed for your hair type. Melissa Kanchanapoomi Levin, a dermatologist, suggests this measure to avoid undesirable results.
Choosing the right bleaching kit: Select a kit specifically designed for dyed hair or one that is gentle and moisturizing. Kits containing bond builders can help protect hair during the bleaching process. Research and read reviews to find products that cater to sensitive or previously treated hair.
Applying the product carefully: Start applying the bleach on the ends, which usually process more slowly, and work your way up to the roots. Use a brush for even application and section your hair for better control. Follow the manufacturer’s instructions regarding development time, and never exceed the recommended duration to prevent further damage.
Managing expectations: Understand that previously dyed hair may not lighten as evenly as virgin hair. Be prepared for potential color variances. Achieving a lighter shade might require multiple applications, spaced out over time to avoid excessive damage.
Hydrating and caring post-bleach: After bleaching, restore moisture with deep conditioning treatments. Hydrated hair is crucial for maintaining health and shine. Consider products enriched with oils or proteins designed for color-treated hair to support recovery.
By following these steps, you can minimize risks and achieve a more satisfactory result when using a bleaching kit on previously dyed hair.

What Precautions Should You Take When Using a Bleaching Kit on Dyed Hair?
The precautions you should take when using a bleaching kit on dyed hair include conducting a patch test, choosing the right product, preparing your hair, and following the application instructions carefully.
- Conduct a patch test

- Prepare your hair properly
- Follow application instructions carefully
- Monitor the process
- Use a deep conditioner post-bleaching
- Seek professional help if unsure
To better understand these precautions, let’s explore each point in detail.
-
Conduct a Patch Test: Conducting a patch test is essential before bleaching. A patch test involves applying a small amount of the bleaching product to a discreet area of your skin or hair to check for any allergic reactions. The American Academy of Dermatology recommends this test 48 hours prior to application.
-
Choose the Right Bleaching Product: Choosing the appropriate bleaching product is key. Different products are designed for specific hair types and existing color levels. For instance, if you have previously dyed hair, it is vital to select a bleach formulated for use on colored hair. Products containing gentle ingredients will be less likely to cause damage.
-
Prepare Your Hair Properly: Preparing your hair properly is crucial for optimal results. Stain removal, using sulfate-free shampoos, and avoiding heat styling in the days leading up can enhance the overall health of your hair. Healthy hair absorbs product better and minimizes breakage during the process.
-
Follow Application Instructions Carefully: Following application instructions is important when using a bleaching kit. Each product comes with its unique guidelines regarding time and method of application. Adhering closely to these instructions prevents over-processing, which can lead to severe hair damage.
-
Monitor the Process: Monitoring the bleaching process closely can help assess the outcome before it becomes too late. Timing is critical, as leaving bleach on for too long can cause hair to become brittle or excessively light. Many experts suggest setting a timer and frequently checking the hair’s color during the process.
-
Use a Deep Conditioner Post-Bleaching: Using a deep conditioner post-bleaching helps restore moisture and strength to damaged hair. Bleach can strip natural oils from hair, making it necessary to replenish these oils. A deep conditioning treatment will provide essential nutrients and support recovery.
-
Seek Professional Help if Unsure: Seeking professional help is advisable if you are uncertain about the process. Professional hairstylists can assess the condition of your hair, suggest the best products, and execute the bleaching safely. Professional intervention can reduce the risk of mishaps.
